NOVELTY - Producing composite powder involves mixing nano-carbon powder with dispersant and water to prepare nano-carbon solution. The graphene powder is mixed with dispersant and water to prepare graphene solution. The nano-carbon solution and graphene solution are used in high-pressure spray nozzle for spraying to form a composite of graphene and nano-carbon material composite solution. The obtained composite solution is spray-dried to obtain final product. USE - Method for producing composite powder (claimed). ADVANTAGE - The method enables to produce composite powder, which fully exerts synergistic effect of nano-carbon and graphene, and improves performance of tire and rubber product containing a large amount of regenerated rubber powder and carbon black.
